Thanks for reporting this. I’m not sure what is preventing the add-on from working on 2.0.
I see the maintenance of this add-on had been taken over by @mrstegeman from its original author, but Mike is no longer able to contribute.
I have filed an issue on the original repo, but I think it’s likely this add-on will need a new maintainer in order for it to be upgraded for use with 2.0.
In the meantime we should list it as working with maximum version 1.1.
